  • Patent number: 5618161
    Abstract: A stationary vane assembly for a turbo-machine in which the vane is restrained against motion in the circumferential direction by first and second locking pins. The second locking pin extends radially through a turbine cylinder and engages a notch in a downstream support rail formed on the vane outer shroud. The first locking pin is affixed to the front radial flange of the cylinder and has a projection that extends into a notch in an upstream support rail formed on the outer shroud. An over-sized slot in the first locking pin allows the circumferential location at which the first locking pin is fixed to the cylinder to be adjusted, thereby ensuring that the first locking pin can be pre-loaded against the outer shroud notch at assembly in a manner that will allow it to restrain the motion of the vane.
